Quality

Content

35%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is a lean catalogue/pointer entry that advertises an upstream skill rather than containing the workflow itself. It is reasonably concise and organized but provides no executable guidance for the actual task and offloads all detail to an external repository.

Suggestions

Add concrete install/clone commands and a minimal runnable PptxGenJS example so the skill is actionable without leaving the file.

Replace the external-URL-only reference with a clearly signaled local reference or bundle so navigation is one level deep and self-contained.

Number the workflow steps and add a verification checkpoint (e.g., confirm the upstream skill is installed and invokable by name).

DimensionReasoningScore

Conciseness

The body is short and free of concept-explanation padding, but the "What it does" section restates the frontmatter description verbatim and the meta catalogue commentary could be tightened.

2 / 3

Actionability

There is no executable guidance for creating or editing presentations; the only command opens a webpage and the rest directs the agent to fetch instructions from an external repo ("Inspect the upstream README for exact paths").

1 / 3

Workflow Clarity

A rough implicit sequence (inspect upstream, install bundle, invoke by name/trigger) exists in prose, but it is not a numbered, checkpointed workflow and the real steps are deferred upstream.

2 / 3

Progressive Disclosure

Sections (What it does, Source, How to use) are organized, but the only reference is an external GitHub URL rather than a clearly navigable local bundle, and exact paths are deferred to the upstream README.

Description

57%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description carves out a clear, distinct niche (PowerPoint generation via PptxGenJS) with concrete actions, but it omits any explicit "Use when..." trigger guidance and only partially covers the natural terms a user would say. Adding trigger phrasing and a broader action list would raise the weaker dimensions.

Suggestions

Add an explicit "Use when..." clause naming presentation-creation triggers (e.g., ".pptx, slides, decks, speaker notes").

Broaden the action list beyond "create and edit" to include specifics like layouts, charts, and speaker notes for fuller capability coverage.

Include common user-facing trigger terms such as "PowerPoint", ".pptx", "slides", and "slide deck" directly in the description.

DimensionReasoningScore

Specificity

Names the domain and two concrete actions ("Create and edit") plus the specific tool (PptxGenJS), but the action set is not comprehensive enough for a 3.

2 / 3

Completeness

It clearly states what the skill does, but the "when to use it" half is absent with no explicit trigger guidance, capping completeness at 2.

2 / 3

Trigger Term Quality

"PowerPoint presentations" and "deck" are natural terms a user might say, but there is no "Use when..." clause and common variations like ".pptx", "slides", or "slide deck" are missing.

2 / 3

Distinctiveness Conflict Risk

The PptxGenJS / from-scratch deck-generation niche is clearly bounded and unlikely to trigger for unrelated skills like PDF or document processing.
